AUTOMATIC DRIVING-GATE.

SPECIFICATION forming part of Letters Patent No. 279,063, dated June 5, 1883.

Application filed January 29, 185.3. (No model.) v

To all whom it may concern Be it known that I, FRANK WILLARD, a citizen of the United States, residing at Meadville, in the county of Linn and State of Missouri, have invented a new and useful Automatic Driving-Gate, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to. automatic gates; and it consists in certain improvements in the construction of the same, which will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, Figure l is a perspective view of my improved gate, showing the same closed. Fig. 2 is a vertical transverse sectional view, showing the gate open, and Fig. 3 is a vertical longitudinal secti onal view.

The same letters refer to the same parts in all 1 the figures.

AAin the drawings represent two pairs of uprights or posts, between which the two pan els B B, which constitute the gate, are pivoted by means of pins (l at their lower rear corners. The panels are pivoted between the posts some distance above the ground, and they rest up on a vertically-sli ding sill, D, which is supported between the posts A A, as will be presently more fully described.

E E are posts or uprights arranged some distance in front of the posts A A, and having levers F at their upper ends. The front or outer ends of the levers F carry adjustable weights G, and their inner or rear ends are connected by rods H with the ends of the sill D, which is thus held suspended between the posts A A. The ends of the sill are also connected by rods I with brackets or projections J upon the ends of the gate-panels.

To the sides of the sill D are hinged plates K K, the lower ends of which rest upon longitudinal tracks L, arranged as shown, between the gate-posts.

M is alongitudinal trough sunk in the ground between the tracks L to receive an upright, N, which is hinged centrally to the under side of the sill D. The front and rear sides of the said upright N are connected by chains 0 with the lower ends of trip-levers P P, hinged at the ends of the trough M, and projecting above the ground and provided with bails Q, so as to be readily and certainly struck and tilted by passing vehicles.

The lower ends or edges of the plates K may be provided with friction-rollers R, moving upon the tracks L. I

The operation of this invention will be readily understood from the foregoing description, taken in connection with the drawings hereto annexed. hen a vehicle, in passing, strikes and tilts either of the trip-levers I the latter serves to tilt the hinged upright N and draw it partly from under the sill D. Pressure be ing simultaneously applied to the hinged plate K on one side of the sill by the horses stepping upon the said plate, the weight of the gatepanels and of the weighted levers is overbalanced, and the gates are thrown open, and the sill and its hinged plates depressed to the position. shown in Fig. 2 of the drawings. XVhen the vehicle has passed through the gate and the pressure upon the plate K ceases, the weighted levers serve to lift the sill, thus closing the gates and drawing the hinged upright N to its original. vertical position. hinged upright, it will be seen, serves to sustain the sill ina raised position and prevent its being lowered and the gates from opening unless the triplever has been operated so as to draw the said upright partly from under the sill. Hence it will not be possible for cattle to open the gate.

I claim as my invention and desire to secure by Letters Patent of the United States The said 1. In a carriagc gate, the combination of two pairs of vertical posts or uprights, the gatepanels pivoted between the same, a sill sliding vertically between said posts, uprights arranged in front of the said posts and having levers, weighted at their front ends, and having their rear ends connected with the ends of the sill, and rods connecting the ends of said sill with proj ections upon the rear sides of the gate-panels, substantially as set forth.

2. In a carriage-gate, the combination of two pairs of vertical posts or uprights, the gate panels pivoted between the same, a sill sliding vertically between the posts and'having its ends connected with the rear ends of the gatepanels, weighted balance-levers connected to the ends of the said sill, and plates hinged to IOCK) the sides of the latter, by pressure upon which it may be depressed, so as to operate the gates, as set forth.

3. In a carriage-gate, the combination of two pairs of vertical posts or uprights. the gatepanels pivoted between the same, a sillsliding vertically between the posts and having its ends connected with the rear ends of the gatepanels, weighted balance-levers connected to the ends of the said sill, plates hinged to the sides of the latter, by pressure upon which it may be depressed, so as to operate the gates, an upright hinged to the under side of the said sill for the purpose of sustaining the latter in a raised position, and mechanism for tilting the said upright from under the sill, substantially as set forth.

4. In a carriage-gate, the combination of the vertically-sliding sill having hinged plates, and having its ends comieeted with the pivoted gate-panels, which are operated by the vertical movement of the said sill, the upright hinged to the under side of the said sill, which may thereby be sustained in a raised position, a longitudinal trough arranged to receive the said upright, trip-levers pivoted at the ends of the said trough, and chains connecting the said trip -levers with the hinged upright, as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

, FRANK \VILLARD.
